Tiiisinvention relates to a machine for renovating sheet inet-zii, und psricuisrly so u machine for cleaning and straightening the tin pistes enxpioyed in the manufacture of tin cans.

In the manufneturing operations necessary to produce the containers for certain classes of goods, the surface of the tin is psinred, iitho'gruphed or printed previous to its being cutund made up into cans. In this operation the sheets have to be hanciied very carefully to avoid niarring them before they nre dried., us Weil us to avoid sera tciiing iiieni und thus damaging zheir finish afi/er they nre dried. Frequenibiy, however, the dried und inished Sheets become biistered, rubbed, s( 'ut-cheri o1' isnt, before being cut up 'und This necessitates discard ingr the damaged sheets und seiiing rhein :is scrap :it ai. fraction of their-oost. it is to overcome this great waste und ehe consequent loss of money, Linie and rubor ocousinned thereby, thai; have devised Athe inuchine forming the subject matter of this invention.

in, descrihingmy invention I wiil take up the' units in the' ori'ier above indicated, with the. eieinents contained in each unit, de-

scribed in sequence oitheir operation upon the sheets passing through the machine.

Unit Aconsisting of the primary straightsuing mechanism und the scrubbing mechanism, is. buiit upon u frmnwwork-14 consistving of u bed 14 supported by legs ill". The

ned

bed is built in the shape ot a reservoir to be presentlv more iultly described, with a series of `iournal bearings spaced along its sides for a series or' sheet rolls 16 between and by means ot' which the. sheet is passed 'through this unit of the machine. As the sheet is started in its passage through the machine, the first set of sheet rolls brings it into engagement with a series oi lingers 1T rotatively mounted upon the shaft 1S of the upper 'feed roller ot the first set. The blocks 1S) which carry the fingers 17 are connected with levers secured to a rotatively mounted shaft '21, by means of links 22. lhe shait 21 extends transversely ol the machine and is provided at one end with a pau'l 223 a lapted to be moved into engagement with the teeth et' a ratchet '24 secured f the shaft 3 of straigliteninj.;r rolls or bars between which the sheet passed. These t :s are corrugated as shown in Figs. 3 and S, and are adapted to straighten turned oversedges of the sheet passing bet-'Ween them, when they are held stationary. Honh ever, these rolls are rotatively mounted in bearings 2?' formed on the ides of the rcsn eri'oir, one end oi' the shaft 25 extending through ont` of the bearings and having a pinion Q8 ricti-onallyT secured thereto by means ot a yielding tension device 29, for the purgose of driving the relis when a sheet is passing between them and 'for permitting of the rolls being stopped when a sheet has passed from beneath the ingers 1T. Both the upper and lower straightening; rolls are provided with pinions which intermtsh, so that both rolls will be rotated in unison, the pinions boing olxierativcly connected with the mechanism employed for rotating the shaits .18 of the first set of feed rolls. The fingers 17 normally7 extend below the line of passage of each sheet as it passes between the iii-st set of feed :rolls and the sheet straightener, so that when the sheet engages thc fingers they will be lifted and thus cause the levers Lv() to lift. the pavvl 2515 out of engagement with the teeth of the ratchet 2% and permit olf rotation of the corrugated rolls. As soon however, as the edge of the sheet is reached, the fingers drop and stop the straightener rolls 2G, thus causing the sheet which has entered betwee 'the second set of sheet rolls, to be pulled between the stationary corrugated straightening rolls 26, the pawl 23 having been brought into engagement with .the teeth of the ratchet 24 to hold the corrugated rolls stationary, after the Afingers 17 have dropped from the edge oi' the sheet. lu this operation any turned up edges of the sheet, will he straiglitcned out and proven. d from hocoining creased or folded as would have oc curred had'the sheet been passed entirely tlrouygh the machine iv out hm-inf o en ightened irst. it Tvill be notie that radi.

Licence the sheet. rolls which operate to pull the sheet between the straightening rolls are so formed as to grip the entire surface of the sheet and thus prevent the sheets slipping when the straightening rolls ,are held stationary by the pawl 23. This is for the reason that the straightening rolls exert a tension on the sheet which smoothes out any wrinkles or turned over edges or corners. The iirst set ot sheet rolls 31 consists oi' two pairs or' disks having yielding tires With Set screws 32 for adjusting them along their 'moiuitinsf shafts 1 8 in order to accommodate themselves to di lierent widths of sheets. The mechanisnii is so designed that 1t 1s preferably the last edge of each sheet that `is subjected to the ironing or straightening elieet of the rolls QG when they are stopped.

Yoilowing the sheet rolls is ascrubbing mechanism consisting of a. transversely reciprocating brush which moves rapidly across the surface of the sheet-s passing through the machine. This brush is reciprocated by means of a connecting rod 34: hav in g rotative connection with a crank 35 mounted on a shaft 36 journaledin bearings 3? secured to the side of the frame of this portion oi the machine. Rotation of the shaft 3G and conseipient reciprocation of the brush is secured by mechanismto be more fully hereinafter described. In order to secure suihcient pressure of the brush 33 upon the sheet passing through the machine and in order at the saine time to permit a free movement of the brush across the sheet with out in any Way adecting the ease of drive oi the crank 35 and connecting rod 34,31 ha ve provided arms 238 secured to the brush carrier 33 and which extend beyond the sides of the frame and which are alined over arms 39 bolted to the sides of the frame inrmediately beneath the arms 38. Connecting theJ arms 38 and 8S) are spring bolts 40, the bolts being pivotally mounted at the ends of the arms 39 so as to be ree to swing the-reni, and at their upper ends are provided 'with springs 41 anda suitable adjustment means `which bring the springs into tension agai st the arms 3S of the brush and consequently force the brush onto the surface of the sheets. `With this pressure reguiating device the brush may move freely across the sheet and at the same time be subjectcd to a substantially uniform pressure thereon. In addition to this means of adjusting the pressure of the brush upon the sheets, i have provided adjusting screws 33a in the backs of the brushes, by means of which the brush blocks 331 (see Fig. 10) may be moved toward or from the surfaces of the sheets. as desired. 'lhe brush blocks I prefn erabl y provide in sections, so that the brush raar he made to extend only over the width of he s passing' through the machine, thus making them adjustable forthe differrooy Y ceives its driving power.

provided for the purpose worm is rotated by means of a hand wheel 74 mounted on the shaft 7 5 to which the worm is secured. .After the accumulation of paint and other material scrubbed from the sheets has become. such'that the reservoir is substantially full, hand holes 92 and 93 are opened for permitting the reservoir to be emptied into buckets and to permit the contents to be suitably disposed of.

The mechanism for driving the feed rolls, the reciprocating brushes, the rotating brush, and the straightening devices, will'be described. Each of the feed rolls is provided with a pinion 76, and .lower roll of each side intermeshing so that the rolls will be driven in the same direction at their point of contact. Outside these pinions and preferably secured to the shafts of the lower' feed rolls are gears 77 which mesh with a series of worms 78 spaced along a drive shaft 79 journaled in bearings 80 longitudinally alinedon the side of the reservoir 14a. Secured to the endof the shaft 79, which is located at the delivery end of the unit A is a sprocket 81 and a drive pulley 8:2 from which the machine re- The sprocket 81 is connected by the chain 83With a sprocket 81 which is secured to a shaft 85 extending on the opposite side of the machine to the point where the crank shaft 36 which affects reciprocation of the brushes 33 and 50, is rotatively mounted. Power from the shaft 85 is communicated to the crank shaft 3G by means of a series of intermeshing gears 86, 87 and 88. ln order to drive the straightening rolls Q6 a gear 89 mounted on one of the shafts 18 of the first set of feed rolls 31 is of meshing with the pinion 28 which is frictionally' connected with the shaft 25 of the upper one of the straightening rolls. At the drive shaft end of the bed intermeshing pinions 90 and 91 are provided for permftting of the rolls being driven in unison. The means employe for driving the rotating brush 55 which scrubs the under surface of the sheets consists of two spiral gears 91 which communicate power from the driving shaft 7 9., transversely of the gears 95 located on the opposite side of the bed, one of whichv is secured to the shaft of the brush 55.

A modified form of device is illustrated in Figs. 13 and 14, this device consisting of two bars 96 and 97 bent at an angle with the apex located in the center of 'the bed and extending in the direction from which the sheets are coming. The bars are spaced apart a suflicient distance to permit of the passage ofthe sheets between them. In this construction the action is to cause I the turned up corners and other wrinkled or turned over portions of the sheet, to be straightened out, as shown in sheet straightening the pinions of each upper l the unit B, secured to a shaft 101 also extending trans-- machine to intermeshing dotted lines inFig. 13, the bars acting as a plow for pushing over the turned up edges and thus straightening the sheet. In this construction the gears 28 and 89, and fingers 17, as well as the pawl 23 and the friction device 29, are eliminated.

The mechanism for rinsing the sheets will now be described.

The rinsing mechanism, the wringing mechanism, and the primary planishing mechanism, are embodied in the single unit B. After the sheets have been passed from the unit A onto the fingers 58 thereof, they are dropped onto a series of rolls 96 located materially above a set of conveyer chains 97 passing from sprockets 98 secured to a sha-ft 99 extending transversely of the frame of and over a series of sprockets 100 versely ofthe frame ofthe unit B. The fra-me of the unit B is made into a reservoir 102 adapted to contain rinse water, and the Shafts 99 and 101' are journaled in bracket bearings 103 and 104 respectively, secured to the inner sides of the reservoir. The bracket 104 is however, located adjacent to the bottom of the reservoir while the bracket 103 is located adjacent to the top of the reservoir. This gives the chain 97 an inclination from the entering end of the reservoir downwardly toward its center, so that the sheets will be brought into the rinse water. .The purpose of locating the rolls 96 some distance above the receiving ends of the chains 97 is to permit the edge of the sheet to bend before it contacts the receiving ends of the chains and thereby dip the forward edge of the sheet under the water and thus prevent its planing across the surface of the water, which would prevent its being properly rinsed. Above the upper end of the 'conveyer chains 97 is located a spraypipe 105 which is arranged to throw a spray onto the sheets dipping into the baths or just previous to entering it. This is for the purpose of forcibly dislodging any clinging particles of solid materialv which may have been loosened from ytheir surfaces and which may have escaped the wiping or scraping devices 44 and 5G, so that when the sheet is immersed in the rinse water the solid :material will be floated therefrom and asa sheet is passed" farther into the bath it will be ilo moved from beneath the floating material these sprockets pass conveyer chains 107a which at their lowest points pass over sprockets 108 secured to the shaft 101 adjacent to the sprockets 100 over which the conveyer chains `\97 pass. The chains 107t are provided for removing the sheets from gli.

'sprocket 122 an l the hath the sheets heving passed down the conveyer chains 97 to the. hottoro oit the beth., The bottoni of the reservoir 102 oi? the rinsing mechanism is provided with e. drain pipe L10 which is provided for `suitehiy draining the reservoir. At the end ot the reservoir e small drip pan 141' which is stt-ached thereto and which communi fates hy means of en elbow )ipe 1&2 with another diem pipe 143 is provided beneath the .fringer end plnnishing rolls for receiving the Water dropping thereiiron'i. The drain pipes 140 and 143 may be suitably closed by means oi' Stoppers or similar devices.

Connecting the shaft 106 and the shaft-s 109 of a set of sheet rolls 110 located over the edge of the reservoir, are n series oi' gears 111, 112 113, 114 ond 115 through which power .from the shafts 1G is coinmunica'ted to the shaft 106 for driving the conreyer chdins 107 and 97. These feed rolls 110 pass the sheet from the conveyer chains 10T onto e series of fingers 116 which etend therefrom to the Wringer 1nd pini'shing rolls 117. The rolls 117 are preferably made of a suitable material, such as nickel steel, which Will withstand greet pressure and ect as planishing rolls :is Well oswringing rolls for squeezing any remaining moisture from the sheets. l'however, the 4planishing eEect is not desired, these rolls Inf-y he of yielding materia-l such ss'rubber which wili act solely es a Wringer for dryinc the sheets'.

By this feeding the sheets between the rolls 141i plenishing rolls isprovided with :tsprocket 11:9 over which passes a. chain 1120 nhich passes over e sprocket 121 secured to one ot the shafts 109 carrying the feed rolls 110. At the opposite end of lthe snuit 118 a sprocket 122 is provided, over which s chain 123 which extends to sprocket 12e on a shaft of the last set of feed rolls 57 ci' the unit A, passes. rhis chain 123, oy this means communicntes driving power to the conse uently to the connested mechanism just described which causes operation ot' the. rinsing, wringing, plenishing mechanisms comprising the unit B. The sheets hes/ing passed :troni the plenishing rolls, are then drying o1' secondary plenishing" mechenisin comprisin' the unit C. This mechanism consists o an oven having u series of ges burners l125 located beneath elliot plate 126 over Which the sheets in their travel through the "drying mechanism. @ver this hot plate is cover plete 12T between `which and the hot plate the sheets are adapted to pass. l'n order to convey these sheets 'over the hot plate und to prevent their contact therewith, a series ot chains 198 "rre pro vided, these chains i 'ng over i329 and 130 located And et The respective spro" :and mounted on shafts schets the oven. lil() ere the shaft nitty here to be p passed through the` Ineens the conveyer chains 128 of the drying mechanism, are driven. From the oven the sheets are then removed in e substantially iinished condition. if it be desired to carry the iinishingor planishing operetion still further, for the purpose o1 removing any traces of material on the sheets, sich as dust left't after the secondery plenishing operation, :is well as to gire-the sheets e polished surface, l have provided the unit D, which consists et' e. series' oi butiing rolls 1114, 145 and 146, which are nrefeebly covered With sheep skin, and which rotate et a high rate oi' speed. Feed rolls lei? ere employed for and if. and feed rolls 14S are employed for eeding the sheets between the rolls 1&5 and 1&6. ine rolls L17 and 148 ere, however, iocsted on opposite sides of the rolls 14A, 1&5 end l1-6, e receiving .and directing plutorni 149 being employed tor catching the sheets delivered from the rolls 144 and 145, und then delivering them to the feed rolls lig.

Suitable mechanism such es the conveyer belt 13 at the entering end of the unit and similar ineens at the delivery end of the unit D, are provided fon conveniently feeding the sheets to and delivering them from the machine. At one side of the conveyer 136 l preferably locnte e. gage plete 138 which adjustableon cross bers 139 so that it muy be positioned in e manner such that the sheets will be fed evenly through the machine, for the Varying sizes which ssed therethrough.

Before passing the sheets through the inn,- chine they ere'preterebly treated in o lye bath tor the purpose of so'ftenine the peint end other materiel contained tl een inorder that the brushes may easily neuve these materials, The' operation of the ninchine upon the sheets is obvious from the obere description end therefore needs no elaboretion, but in order to aid in more clearly understanding the reason 'for providing; more 'than one scrubbing device whichnioves in more than one direction over the seine side of 'the sheets, und for providing but one scrubbing device for :noting in but one direction over the other side ot' the sheets, it may be explained that the tin sheet used in the manufacture of painted, printed oli iithogruphed cans, is lithogrnphed, painted or printed on but one side.
